CARBURETER.

To all whom it may concern:

Be it known that I, WILLIAM H. BROWN ING, a citizen of the UnitedStates, and a resident of Rye, in the county of Westchester and State ofNew York, have invented a new and Improved Carbureter, of which thefollowing is a full, clear, and exact description.

The object of the invention is to provide a new improvedcarbureter, foruse in gasos' lene and like explosive engines, and arranged to permitconvenient and accurate adjustment of the needle valve by bodily movingthe same instead of turning and screwing the needle valve in or out, andto hold the members of the air admission valve in firm contact with eachother by the suction of the engine in drawing in the air.

For the purpose mentioned use is made of a manually-controlled devicefor movmg the needle valve bodily toward and from its seat to govern theflow of gasolene or other liquid, and an air admission valve is mountedto turn andpressed on by a spring and by the suction action of theengine to hold the air admission valve in contact with its seat.

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in bothviews Figure 1 is a sectional side elevation of the carbureter on theline 11 of Fig. 2; and Fig. 2 is a plan view of the same.

The carbureter casing A is provided with a top plate B having one ormore openings B for the passage of air into the casing A, and the saidtop plate B is provided with a central upwardly-extending flange Bengaged by the hub C of an air admission valve 0 resting on the uppersurface of the top plate B and having openings C adaptedto register withthe openings B to control the amount of air passing into the cas ing A.The air admission valve 0 is pro- 'vided with a handle D under thecontrol of the operator for turning the valve G to move the openings Cin more or less register with the openings B for the purpose specified.Theturning motion of the admission valve G is limited by stops E, E heldon the side of the casingA and adapted to be engaged by -the handle D.Thus Specification of Letters Patent.

when the handle D is against the stop E, the admission valve iscompletely open, and when the handle D abuts against the stop E theadmission valve is completely closed.

In the flange B screws a tube F provided at its lower end with a valveseat Gr connected with a pipe H extending through the side of the casingA to the outside thereof to connect with a source of gasolene or otherliquid supply. The valve seat G is controlled by a needle valve I,having its stem I threaded and extending centrally through the tube Fand its cap plate F, as plainly indicated in Fig. 1, and on the stem 1screws a collar J fitting into the tube F and p essed on by a spring Kheld in the upper portion of the tube F and abutting with its upper endagainst the cap plate F while the lower end of the spring engages thetop of the collar J to press the latter downward and with it the stem Iand the needle valve I.

On the top of the cap plate F is mounted to turn a face cam N having ahandle N under the control of the operator, and the face cam N isengaged by an arm 0 guided vertically on a guide pin P attached to thetion of the threaded stem I of the needle valve I, and slidinglyengaging the arm 0, face cam N and cap plate F, and on the outerend ofthe collar Q screws a nut R resting on top of the arm 0 so as to limitthe downward movement of the needle valve I. Now when the several partsare in the position as shown in Figs. 1 and 2, the needle valve I isheld completely open, and when it is desired to close or partly closethe needle valve I then the operator turns the handle N in the directionof the arrow a so that the arm 0 rides downward on the face cam N,whereby the threaded stem I of the needle valve I is allowed to movedownward by the action of the spring K pressing on the collar J to movethe needle valve I down toward the seat- G. It will be seen that by thearrangement described the stem I and the needle valve I are bodily movedin an axial direction on the operator turning the face cam N so thatscrewin up of the needle valve stem is not require for adjusting theneedle valve relative to its seat, as heretofore practised incarbureters as now generally constructed. By adjusting the nut R on thecollar Q the needle valve I may be set nearer to or farther from thevalve seat G when assembling the several parts. The collar J is lockedinplace on the stem I by a jam nut as 1ndicated in Fig. 1. A spring S iscoiled around the tube F and rests with its upper end on the under sideof the cap plate F, while the lower end of the said spring S presses ontop of the admission valve 0 so as to firmly hold the latter down on thetop plate B of the casing A, to compensate for all wear between theconducting surfaces of the valve G and the top plate B. It will alsobenoticed that when the carbureter is in use, the suction action of theengine 1 n drawing in the air causes the entering air to exert apressure on the valve C to aid' the spring S in holding the admissionvalve C in contact with the top plate B.

The bottom of the casing A is provided with an outlet T connected withthe engine, and above the said outlet T and directly below the needlevalve seat G is arran ed a conical spreader U having a non-perforatepoint or apex U and a perforate body portion U so that the gasolene orother llquid 'flowing down the seat G drops onto the nonperforate apex Uto be spread by the same onto the perforate body portion U to be takenup by the air entering the openings B, C and passing through theperforate portion U to the outlet T. The spreader U is supported by armsV from the bottom of the casing A so that the base of the spreader is adistance above the outlet T, as plainly indicated in Fig. 1.

Fromthe foregoing it will be seen that by the arrangement described, theoperator can properly control the admission of the air and that of thegasolene by operating the' handles 1) andN correspondingly.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1.
